3. _C_h_a_n_g_e_s__a_n_d__A_d_d_i_t_i_o_n_s
The following changes were made to the IRIX NFS 4D1-6.2
product.
+o AutoFS and CacheFS were added to the NFS product.
+o autofs is now chkconfig'ed ``on'', by default. If
autofs is ``on'', the network script will run autofs
(and not automount), regardless of the chkconfig
setting for automount.
+o The default configuration was changed so that AutoFS
uses NFS V3 (backing off to NFS V2, if necessary).
+o AutoFS now supports the use of NIS maps in its
configuration.
+o AutoFS recognizes the nodev mount option. This is now
part of the default configuration.
+o Recognition of the $CPU and $ARCH environment variables
has been added to AutoFS.
+o The disk layout for the cached data and the metadata
used by CacheFS have changed. Thus, when upgrading
from earlier versions of CacheFS, it will be necessary
to remove the cache directory. This should be done
with the "rm -rf" command as the entire contents of the
cache directory must be removed. Once the IRIX 6.4
version of CacheFS has been installed, it will not be
necessary to run cfsadmin(1M) to recreate the cache.
This will be done automatically. If different cache
parameters from the defaults are desired, cfsadmin(1M)
may be used.
+o An option has been added to mount(1M) (the -m option)
to allow the number of parallel mount processes to be
limited. This should be used with cachefs on systems
where some cachefs mounts fail due to a lack of swap
space. The -m option and its argument should be placed
into the file /etc/config/cachefs.options. The
contents of this file are used as the options to mount
for mounting cachefs file systems.
+o The default transfer size for NFS V3 is 32k bytes. The
maximum transfer size is 48k bytes. The system
requires that the transfer size be a multiple of 512,
and enforces that by rounding down a transfer size to
the nearest multiple of 512.
